7 questions

1

Define the term "coefficient of friction" and explain what it represents in the context of an object on an inclined plane.

2

Explain why the normal force is equal to mg⋅cos(θ) for an object on an inclined plane. Use a free body diagram to support your answer.

Quick comprehension check

A 10 kg box is placed on an inclined plane that makes an angle of 20° with the horizontal. The coefficient of friction between the box and the plane is 0.3. Calculate the force of friction acting on the box. Show all work. A 25 kg block rests on an inclined plane with an angle of 45°. If the coefficient of friction between the block and the plane is 0.15, calculate the force of friction acting on the block. Show all work.
